Plugin development problem

Hello
I am quite new to plugin development and i am working on a kitpvp plugin for my server but i have one error that i can't figure out or find on google how to fix so thats why I am making this thread.
The error says "The method command() is undefined for the type Main"
Heres a part of the code: public class Main extends JavaPlugin {
private Events Events = new Events(this);
ArrayList<String> Pvp = new ArrayList<String>();
ArrayList<String> Fisherman = new ArrayList<String>();
ArrayList<String> kitused = new ArrayList<String>();


public void onEnable() {
commands();
events();
The "commands();" part has the error
It's probably an easy fix and many of you will facepalm reading this but please help.

Like the error says; commands() is not a Method, and theredore cannot be executed.
